Bug warning!
Do not complete the quest from Whiterun to kill the bandit leader at Valtheim Keep until you have been to speak to The Companions leader and got the quest "Trouble in Skyrim", which tasks you with killing the same Bandit leader at Valtheim Keep.
Because I just picked up "Trouble in Skyrim" and found that I cannot complete it because I have killed them already....
I'm hoping it's not a major quest line and I can get a long without it. I have read via google that someone else had this problem and it fixed itself over time.
Beggar, I've done that quest! Hard not to when it's one of the first quests you get in Rivendell (or whatever it's called).
